FILLING-VALVE FOR SYRUPERS.

To all whom it mag concern:

Be it known that I, ALBERT R. THOMPSON, a citizen of; the United States, residing at San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Filling- Valves for Syrupers, of which the following is a specification.

My invention relates to the general class of syruping machines used in the canning art, and particularly to a filling-valve-structure, the object of which is .to. automatically provide for the requisite volume of the syrup in the cans, preparatory to their introduction into the exhaust-box.

A further object is to provide for the variation of this volume according to circumstances, and also to avoid undue. pressure upon the relatively solid contents of the cans while being filled.

To these ends my invention consists in the novel filling-valve structure, which I shall hereinafter fully describe by reference to the accompanying drawings, in which I have deemed it suflicient to illustrate my inventionin a single instance and in connection with only so much. of the general fea tures of a syruping machine as are necessary for an understanding of the filling-valvestructure, it being apparent that the details of the syruper per 86 have no bearing on the present case and may be of any suitable character.

In the drawings- 4 Figure 1 is a vertical sectional elevation of my device.

Fig. 2 is a horizontal section on the line '22 of Fig. 1.

1 is the syrup tank, having depending therefrom an outlet fitting 2 with a foot flange 3. Upon the outlet fitting 2 is slidably mounted the valve 4, with a gasket 5, and said valve is held normally down by a v spring6. The face of the valve is a rubber ring 7, against which the can 8 presses, with the elfect, when the can is elevated, by suitable means, here shown for illustration as a table 9, having a foot roller 10 which travels on a cam-track 11, of pushing up said valve upon the outlet fitting 2 and against the spring 6,

The interior of the outlet fitting 2 has inwardly projecting spaced arms 12 which carry at their inner ends the stem 13 of the semi-globular or inverted dish-shape valve- Specification of Letters latent. Patented Dec. 241, 1918.,

its top a screw cap 18.

19 is a member, the position off which within the can determines automatically the volume of syrup which can as predetermined. his member has a bell or inverted dish shape conforming to the valve seat 14, and comprises two connected plates separated by an exit air-space or duct 20, which opens out peripherally. Said member 19 lies below the valve-seat 14 and is fitted to the flange 16 thereof for guidance- 1n vertical adjustment. It is carried b a hollow stem 21 communicating at its oot with the exit air-space 20, said stem passing upwardly through the valve-seat stem'extension 17 and through the cap 18 thereof, and

receives an adjusting nut 22 on its top, which top is open to the atmosphere. A stop collar or flange 23 on the stem 21 below the cap 18 coacts therewith in the adjusting movement.

-The operation of the device is as follows :Communicat ion'between the tank 1 and the can 8 is normally closed by the "contact of the valve-seat rim 15 with the valveface 7. But when the can is lifted and by contact with said face 7, lifts the 'valve 4,

said valve face 7 leaves the valve seatrim ay be supplied the I 15 and communication between the tank and can is established.

Syrup now flows into the can, the air escaping through the space or duct 20, and hollow stem 21 to the outer air. When the syrup in the can reaches'and covers the peripheral entrance to the air-space 20, there will still remain in the can, under the dish syrup, so that in practice the syrup level only reaches the top of the can'around the member 19 and the valve-seat flange 16, and to a corresponding level'in the air-duct 20, before the communication between the tank 1 and the can is cut oil by the lowering of the latter. The air duct 20 being relatively of small capacity, but little back drip therefrom takes place when the can is lowered, and this small amount of drip, plus the relatively small volume of syrup reaching the top of the can around the flange 16' and.

member 19 is designedly less than the vol ume excluded by the confined air .under the bell of the member 10, so that the can never ment of said member 19, which is efi'ected by properly manipulating the cap 18 and the nut 22.

The concave or inverted dish-shape of the member in addition to its chief function of providing for a displacement air-body is of advantage in that it presents minimum obstruction in the can, and permits the relatively solid contents to rise above the liquid level without injury. The solid contents thus rising into the bell of the member 19. is provided for in the predetermined ratio of the capacity of the displacement air-body to the space outside, so that the volume of the displacing air is still sufficient to prevent an excess ofsyrup;
